It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] like Figure 1-6 As shown, a dust bag cleaning device comprises a base plate 1, a bracket 2 is welded on the top of the base plate 1, two lifting motors 3 and a rotating motor 4 are installed above the bracket 2, the output ends of the two lifting motors 3 pass through the bracket 2 and are fixedly connected with screws 5, the bottom ends of the screws 5 are connected to the base plate 1 through bearings 6, the two screws 5 are commonly threadedly connected with a fixing ring 7, a cleaning brush 8 is fixedly connected to the inner wall of the fixing ring 7, a scraper 9 is fixedly connected to the bottom of the fixing ring 7, a strip brush 10 is fixedly connected to the output end of the rotating motor 4 after passing through the bracket 2, a base plate 11 is slidably connected to the base plate 11, a fixing column 12 is fixedly connected to the base plate 11, the fixing column 12 is sleeved with a limiting ring 13, the limiting ring 13 is bolted to the base plate 11, the base plate 11 is bolted to the base plate 1, and a handle 14 is welded on the outer side of the base plate 11.

[0027] The two lifting motors 3 are used to lift and lower the threaded fixing ring 7 through the rotating screw 5, so as to clean the side of the dust bag through the cleaning brush 8 and the scraper 9. The rotating motor 4 is used to drive the strip brush 10 to rotate so as to clean the bottom of the dust bag. The fixing column 12 is used to sleeve the dust bag, the limiting ring 13 is used to fix the dust bag sleeved on the fixing column 12, and the base plate 11 is used to support the fixing column 12 and can slide to facilitate the sleeve of the dust bag.

[0028] The rotating motor 4 is located at the central position of the top of the bracket 2, and the two lifting motors 3 are symmetrically located on the bracket 2 on both sides of the rotating motor 4. The output end of the rotating motor 4 is fixedly connected to the rotating rod 15, and the rotating motor 4 is fixedly connected to the strip brush 10 through the rotating rod 15. The bristle end of the strip brush 10 is pressed against the fixed column 12, and the two ends of the strip brush 10 are arc-shaped.

[0029] The fixing ring 7 is in the shape of a ring. The shapes of the cleaning brush 8 and the scraper 9 match those of the fixing ring 7. The center axis of the ring of the fixing ring 7 is in the same straight line as the rotating axis of the rotating motor 4. Fixing plates 21 are welded on the outer walls on both sides of the fixing ring 7. The two screws 5 are respectively threadedly connected to the fixing plates 21. The two screws 5 are threadedly connected to the fixing ring 7 through the two fixing plates 21. A spring 16 is sleeved on the screw 5 between the fixing plate 21 and the bracket 2. The spring 16 can effectively buffer the force generated on the bracket 2 when the fixing plate 21 moves.

[0030] The fixing column 12 is cylindrical, and the central axis of the fixing column 12 is on the same straight line as the circular central axis of the fixing ring 7 .

[0035] The working principle of the utility model is as follows: when in use, the handle 14 is held by hand to pull out the base plate 11, and then the bottom of the cloth bag is put on the fixing column 12 with the bottom facing upwards, and then the limiting ring 13 is put on the outside of the dust bag, and the mouth of the cloth bag is pressed and fixed on the base plate 11 by the limiting ring 13 and the first bolt 17, effectively preventing the cloth bag from sliding when cleaning the cloth bag, affecting the cleaning effect of the cloth bag, and then the base plate 11 is moved back to its original position, and the base plate 11 is fixed on the bottom plate 1 by the second bolt 20, and then the rotating motor 4 is started, thereby driving the strip brush 10 to clean the bottom of the dust bag, and at the same time starting the lifting motor 3 to drive the screw 5 to rotate to move the fixing plate 21, so that the scraper 9 effectively scrapes off the accumulated dust on the cloth bag. After the scraper 9 scrapes, the cleaning brush 8 will further clean the surface of the cloth bag to prevent the fine gaps on the surface of the cloth bag from sticking to dust, thereby effectively increasing the cleaning effect of the cloth bag.
